Fig. 7From: The fate of systemically administrated allogeneic mesenchymal stem cells in mouse femoral fracture healingComparison of the number of the injected Luc-positive cells at the fracture site at 5 weeks following fracture. a The number of Luc-positive cells in the callus in the MSC systemic injection group was significantly lower than that of the MSC local injection group (P < 0.05). b The proportion of apoptotic Luc-positive cells in Luc-positive cells in the MSC systemic injection group was significantly lower than that in the MSC local injection group (P < 0.05). c The proportion of Luc-MSCs in Luc-positive cells in the MSC systemic injection group was significantly higher than that of the MSC local injection group (P < 0.01). d The proportion of Luc-osteoblasts in Luc-positive cells did not show significant difference between the MSC systemic injection group and the MSC local injection group (P > 0.05).
